You can use Excel for your checklists. Many apps promise to handle your to-do list, but do you really need yet another app? Even if you don’t want to use it as an everyday to-do list app, a checklist is a good way to keep track of what you still need to do in your spreadsheet, directly in the spreadsheet itself.

Checklists are provided to serve as a guide to people who need to take note or do a lot of things that may be too much for our memory. It reminds us on things that we need to do as well as the things that we have already accomplished in the past. We bring checklists when we go on vacations to remind us on the things that we need to bring. We also bring them when we go shopping to prevent us from forgetting the things that we need to purchase.
